THREE  PINK  AND  GREEN  APHIDS  OF  THE  ROSE* 

Edith  M.  Patch 

For  many  years  after  Linnaeus  gave  “the”  rose  aphid  the 
specific  name  of  rosae,  this  term  proved  sufficiently  elastic  to 
embrace  all  the  large  green  or  pink  aphids  found  upon  the  rose. 
Just  how  many  of  these  there  may  prove  to  be  when  the  sub- 
ject has  been  entirely  covered  it  is  still  too  soon  to  say. 

It  is  certain,  however,  that  there  are  at  least  three  species 
of  the  genus  Macrosiphum  common  on  the  rose  in  Maine  and 
that  each  of  these  has  two  distinct  color  varieties,  one  pink  and 
one  green. 

Of  these  ikf.  rosae  proper  is  not  known  to  migrate  and  it 
does  maintain  a continuous  residence  upon  the  rose.  This  cir- 
cumstance would  not  preclude  the  possibility  that  it  has  a sec- 
ondary food  plant  which  is  used  as  a summer  resort  for  it  is 
not  uncommon  for  a species  with  a definite  spring  and  fall  mi- 
gration to  and  from  the  summer  food  plant  to  continue  also  to 
colonize  its  primary  food  plant  (that  upon  which  the  overwin- 
tering egg  is  placed)  during  the  summer  months. 

The  second  of  the  pink  and  green  rose  aphids,  Macrosi- 
phurn  solanifolii,  also  deposits  its  eggs  upon  the  rose  in  the  fall 
where  it  may  be  found  in  heavy  colonies  during  the  spring  and 
early  summer,  when  it  migrates  for  the  most  part  to  a great 
variety  of  summer  plants,  though  it  may,  besides,  keep  up  its 
connection  with  the  rose  during  the  summer.  In  Maine,  and 
in  perhaps  most  other  parts  of  the  United  States,  this  species 
works  greater  havoc  in  potato  fields  than  on  other  vegetation. 

The  heavy  infestation  of  the  potato  may  be  encouraged  by 
the  well  nigh  universal  abundance  of  these  plants  putting  forth 
their  most  succulent  growth  at  the  time  M.  solanifolii  migrates 
from  the  rose ; and  its  threat  against  this  crop  is  evidently  a

two-fold  one, — the  direct  damage  due  to  its  feeding  habits,  and 
its  indirect  but  possibly  even  more  serious  harm  of  serving  as 
a carrier  of  potato  disease.* 

As  there  are,  at  present,  no  items  concerning  M.  rosae  in 
Maine  which  are  different  from  those  available  in  publications 
from  other  sources;  and  as  M.  solanifolii  has  already  appeared 
in  several  bulletins  of  this  Station,  the  present  account  will  con- 
cern chiefly  the  third  pink  and  green  aphid  of  the  rose  which  is 
here  described  as  a new  species  though  it  may  prove  to  have 
an  old  world  name  when  its  geographical  distribution  and  food 
plants  are  better  known. 


MaCROSIPIIUM  I’SEUDOROSAE  N.  SIL 

Alatc  viviparous  female:  General  color  polished  rose  red 
or  green.  Beak  short  and  stout.  Antennae  black,  so  heavily 
pigmented  that  it  is  difficult  to  prepare  a mount  which  shows 
the  distribution  of  the  sensoria;  III  with  14  more  or  fewer  sen- 
soria  in  a row  extending  usually  about  five-sixths  its  length; 
IV  without  sensoria;  the  relative  lengths  of  segments  III  to  VI 
may  be  indicated;  13,  ii,  8,  2-I-13.  Fore  wing  with  veins 
slender  and  about  uniform.  Second  joint  of  ist  tarsus  exclud- 
ing claw  about  three-fourths  length  of  base  of  VI.  Cornicle 
deep  black,  usually  not  much  shorter  than  III  or  anal  vein  of 
fore  wing,  though  considerable  variation  is  possible,  and  reticu- 
lated for  about  one-fifth  its  length.  Cauda  yellowish. 

Apterous  viviparous  female:  General  color  same  as  in  the 
.-alate  female,  both  color  varieties  being  common.  Antenna  with 
single  row  of  sensoria  extending  about  half  the  length  of  III, 
sometimes  farther.  (See  also  remarks  on  reared  individuals 
p.  208). 

Descriptions  of  both  of  the  foregoing  are  from  wild  rose 
material  collected  July  19,  1918  by  Mr.  George  Blodget.  Co-

My  attention  was  first  directed  to  this  species  by  a collec- 
tion made  by  Mr.  George  L.  Blodget  from  golden  ragwort 
(Senecio  aureus  L.)  July  3,  1918.  This  material  was  mixed 
with  Macrosiphum  solanifolii  from  which  it  was  easily  sepa- 
rated by  its  black  antenna  and  cornicle.  A second  search  in  the 
same  locality  revealed  the  fact  that  both  these  species  were  also 
present  on  the  numerous  wild  roses  on  the  bank  of  the  Penob- 
scot very  near  the  ragwort. 

Of  course  the  next  step  was  obvious  and  preparations  were 
made  for  transfer  tests  from  wild  rose  to  ragwort.  The  potted 
plants  of  ragwort  were  slow  in  getting  a start  and  only  the 
rosettes  of  basal  leaves  remained  fresh  for  the  duration  of  the 
test. 

By  July  24,  these  plants  seemed  in  safe  condition  to  use 
and  on  that  date  two  viviparous  females  of  the  pink  color  vari- 
ety were  removed  from  wild  rose  and  caged  on  the  ragwort. 
One  was  apterous  and  the  other  alate,  and  both  were  somewhat 
restless  during  the  first  day,  a condition  accounted  for,  perhaps, 
by  the  fact  that  the  new  food  plant  was  making  less  succulent 
growth  than  the  rose  they  had  been  feeding  upon. 

July  26,  both  aphids  were  feeding  head  down  and  both 
producing  young.  Ten  nymphs  present  and  all  were  feeding. 

August  2,  both  aphids  were  still  feeding  and  producing 
young,  30  nymphs  being  present.  Their  manner  was  to  colonize 
one  leaf  and  then  move  to  freshly  growing  uninfested  leaf  or 
to  a separate  plant.  The  apterous  female  was  removed  to  avoid 
overstocking  the  caged  ragwort. 

August  9,  several  apterous  viviparous  females  matured  and 
were  removed. 

August  13,  several  more  mature  apterous  viviparous  fe- 
males were  removed. 

September  12,  the  first  alate  viviparous  female  and  several 
mature  apterous  ones  were  removed  and,  due  to  the  condition 
of  caged  plant,  the  test  was  discontinued. 

The  point  at  issue,  however,  has  been  established.  Cap- 
tives of  Macrosiphum  pseudorosae  were  capable  of  living  upon 
ragwort  and  their  progeny  matured  upon  the  secondary  host 
plant.  There  seems  no  reason  to  question  the  conclusion  that 
the  ragwort  material  first  taken  in  July  had  had  its  origin  in 
migrants  from  the  rose  as  was  the  case  with  Macrosiphum  solan-

ifolii.  And,  as  with  Macrosiphwn  solanifolii,  the  migration  of 
MacrosipJmm  pseiidorosae  was  not  entirely  complete  for  strag- 
glers remained  upon  the  rose  during  the  summer  with  both  these 
species. 

All  of  the  reared  cage  individuals  were  of  the  rose  pink 
color  variety  as,  it  will  be  remembered,  were  the  two  females 
from  which  they  were  descended. 

Plans  were  made  for  continuing  observations  earlier  in  the 
season  during  1919  and  a report  upon  this  interesting  aphid 
was  delayed  with  that  in  mind.  But,  although  the  same  locality 
was  well  patrolled  this  spring  and  summer  not  a single  specimen 
of  Macrosiphum  pseiidorosae  was  found.  It  seems  better, 
therefore,  to  publish  what  has  been  ascertained  with  a view  to 
throwing  open  the  situation  for  comparison  in  other  parts  of 
the  country. 

It  would  not  be  surprising  if  the  name  pseiidorosae  should 
fall  as  a synonym  to  rosaeiformis  Das,  but  material  is  not  avail- 
able for  comparison  and  it  is  too  far  a cry  from  Maine  to  India 
to  risk  on  the  slight  acquaintance  we  have  either  with  the  rose 
— ragwort  species  here  or  the  “Punjab  Rose  Aphid”  described 
by  Das. 

A full  list  of  the  food  plants  in  India  and  America  may 
give  a clue  leading  both  aphids  to  some  older  name.  The  same 
insect  or  one  very  closely  allied  is  found  in  Maine  upon  Geum 
and  Cinquefoil  (Potentilla)  of  the  rose  family  and  upon  certain 
other  members  of  the  Composite  Family  besides  the  golden  rag- 
wort, but  in  no  case  was  it  definitely  ascertained  whether  it  actu- 
ally was  Macrosiphum  pscudorosae  or  a species  closely  resembl- 
ing it  and  a further  acquaintance  with  this  aphid  is  desirable. 

Macrosiphum  pseiidorosae  is  a variable  species  with  refer- 
ence to  several  characters  which  are  usually  available  for  specific 
determination,  such  as  the  relative  length  of  the  cornicle  with 
reference  to  antennal  segment  III  and  the  number  of  antennal 
sensoria.  For  instance  the  individuals  reared  on  Senecio  from 
two  known  females  removed  from  rose  showed  the  following 
variations.  1'he  size  was  in  all  the  caged  individuals,  smaller 
than  their  rose  progenitors  a circumstance  which  might  easily 
be  accounted  for  by  tlie  fact  that  the  basal  rosettes  of  ragwort 
](;aves  were  not  making  succulent  growth.  In  the  apterous  vivi- 
parous females  the  relative  length  of  cornicle  to  111  of  antenna.

about  nine-tenths  remained  approximately  constant  in  most 
cases  though  in  one  of  the  September  individuals  the  cornicles 
were  dwarfed  to  ten-seventeenths  the  length  of  III.  In  this 
same  aphid  there  was  but  one  sensorium  on  III  as  against  3 to 
5 in  most  of  the  ragwort  specimens  and  6 to  8 in  the  summer 
host  collections. 

The  key  given  on  pages  216-218  has  proved  useful  in  sepa- 
rating Macrosiphu'in  psciidorosae  from  other  New  England 
members  of  the  same  genus,  and  is  offered  here  on  the  chance 
that  it  may  be  of  some  slight  service  in  Eastern  United  States, 
though  the  writer  has  not  yet  been  able  to  construct  a key  to 
these  species  which  would  seem  to  be  at  all  adequate  in  view  of 
the  wide  range  of  individual  variation  of  which  these  aphids 
are  capable. 


Several  New  Species 

The  publication  of  the  key  necessitates  the  description  of 
several  species  which  have  been  accumulating  in  the  collection 
until  it  is  difficult  to  handle  them  any  longer  under  manuscript 
names.  Not  enough  is  known  about  most  of  them  to  warrant 
giving  them  much  space  but  it  will  serve  to  put  them  on  record 
with  reference  to  their  food  plants  and  possibly  to  link  into 
data  from  other  collections. 

MACROSIPHUM  CARPINICOLENS  N.  SP. 

Apterous  viviparous  female : antennae,  tibiae  and  distal 
two-thirds  of  cornicle  dark;  frontal  tubercles  very  prominently 
produced;  antennal  segments,  particularly  III  with  curved  im- 
brications closely  set  and  with  serrate  edge  which  give  a dis- 
tinctive character  at  once  noticeable;  III  with  from  one  to  a 
few  sensoria  in  row  near  base,  setae  very  short  and  stubby ; III 
about  two-fifths  the  length  of  hind  tibia;  relative  lengths  of 
antennal  segments  III  to  VI  approximately  indicated  by  50,  45, 
40,  io-j-65 ; cornicle  shorter  than  V with  the  distal  one-sixth 
reticulated;  hind  tarsus  about  three-fifths  as  long  as  base  of  VI. 

This  species  collected  from  the  leaves  of  blue  beech — ( Car- 
pinus  caroliniana  Walt.)  in  the  vicinity  of  Orono  during  June

14,  12,  3+17;  III  with  about  50  small,  distinct  circular  sensoria 
reaching  the  entire  length  of  segment,  IV  with  no  sensoria; 
cornicle  usually  shorter  than  IV  and  longer  than  V and  with 
the  distal  area  of  reticulation  not  more  than  one-sixth  its  length; 
cauda  about  one-third  as  long  as  cornicle ; wings  with  veins 
slender  but  clear  cut  and  definite,  second  branch  of  M rather 
long. 

This  species  was  collected  at  Orono  from  fronds  of  bracken 
fern,  Ptcris  aquilina,  July  3,  1913  (79-13)  ; and  from  lady  fern, 
Athyrimn  filix-foeinina  (180-18).

though  definite  reticulations. 

This  species  was  collected  at  Orono  from  wild  bush  honey- 
suckle (Diervilla  lonicera  Mill.)  by  William  C.  Woods  July  7 
and  July  21,  1915  (Nos.  65-15  and  84-15).

Species  appearing  rather  hairy  in  life,  with  little  dorsal  tubercles 
at  base  of  hairs  on  abdomen  in  transverse  rows.  Coxa,  femora, 
and  ventral  surface  of  head  olive  green ; tibia  and  tip  of  beak 
black.  Comparative  length  of  antennal  segments  III  to  VI 
indicated  by  55,  46,  43,  10+65  1 with  20  to  30  sensoria  rather 
small  and  scattered,  IV  with  no  sensoria,  frontal  tubercles  short

Nymphs  are  glistening  and  not  pulverulent  or  hoary.  They 
are  hair}^,  reddish  and  dark  brown. 

This  species  is  evidently  distinct  from  Macrosiphum  car-

MACROSIPHUM  AMELANCHIERICOLENS  N.  SP. 


Alate  viviparous  female : dark  bodied  with  black  antennae, 
legs  and  cornicles,  and  with  dusky  wings.  Frontal  tubercles 
strong  and  divergent.  Comparative  length  of  antennal  seg- 
ments III  to  VI  indicated  by  55,  45,  38,  10+45.  m with  about 
50  sensoria  scattered  over  nearly  its  whole  length.  IV  with  no 
sensoria.  Cornicle  shorter  than  III  and  longer  than  IV  with

This  apparently  distinctive  aphid  was  collected  in  June  at 
Orono  1914,  from  Amelanchier  spicata  Lam.  I have  never  seen 
it  since.

as  long  as  IV  and  with  its  distal  one-fourth  or  more  reticulated. 

(153-12.) 

Apterous  viviparous  female : general  body  color  stem  green 
and  immaculate.  Relative  lengths  of  antennal  segments  III  to 
VI  indicated  by  55,  40,  39,  io-|-6o.  Ill  with  5 to  8 sensoria 
in  row.  Cornicle  shorter  than  III  hut  nearer  III  than  IV. 
(66-10). 

Apterous  oviparous  female : relative  lengths  of  antennal 
segments  III  to  VI  indicated  by  45,  35,  35,  io-[-65.  III  with  4 
to  8 sensoria  in  an  uneven  row.  Cornicle  about  as  long  as  IV. 
Hind  tibia,  at  widest  part,  double  the  width  of  the  others  and 
excessively  crowded  with  sensoria  (119-06). 

This  species  comes  near  specimens  of  Macrosiphmn  gaurae 
Williams  I have  received  from  the  west  but  is  either  distinct  or 
the  range  of  variability  for  the  species  is  unusually  great.  It 
is  the  common  Macrosiphum  on  evening  primrose,  Oenothera 
biennis  L.  in  Maine  and  inhabits  the  stems  of  the  flower  cluster

“Intermediates”  are  frequent  in  the  collections  of  this 
aphid,  which  except  for  their  wing  stubs  partake  chiefly  of  the 
characters  of  the  alate  female. 

MACROSIPHUM  LANCEOLATUM  N.  SP. 

Alate  viviparous  female : general  body  color  dark  reddish 
brown,  cauda  yellowish  white,  cornicle  black.  Frontal  tubercles 
strong.  Comparative  length  of  antennal  segments  111  to  VI 
indicated  by  45,  38,  35,  10-55.  ^ with  about  30  sensoria  scat- 

tered along  whole  length.  IV  with  no  sensoria.  Cornicle  al^out 
as  long  as  IV  and  shorter  than  beak.  Ill  is  shorter  than  vein 
A of  front  wing.  Reticulation  of  cornicle  covering  about  dis- 
tal two-sevenths. 

Apterous  viviparous  female : general  color  as  in  the  alate 
form.  Ill  with  about  20  sensoria.  Hairs  of  the  head  spatulate 
at  tip.  Cornicle  shorter  than  beak. 

This  aphid  is  sometimes  taken  on  goldenrod,  Solid  ago  lan- 
ce olat  a L.  The  antennae  seem  particularly  brittle  and  are  fre- 
quently knocked  off  at  distal  tip  of  III.  The  wings  are  often 
sport-veined,  M frequently  being  but  once  branched  although 
when  branched  twice  the  second  branch  is  not  especially  near 
wing  margin.  Mr.  Pergande  saw  Maine  material  of  this  species 
about  fourteen  years  ago  and  stated  that  it  was  unnamed.  The 
writer  has  not  succeeded  in  linking  it  with  known  species  and 
so  describes  it  as  new. 

The  paratype  material  (43-05  and  86-09)  is  in  the  collec- 
tion of  the  Maine  Agricultural  Experiment  Station.
